| Description | This article describes how to identify RAID controller failure on FortiAnalyzer hardware appliances. |
| Scope | FortiAnalyzer. |
| Solution |
1) In most cases, when an on-prem device is a hardware appliance and logs are no longer present under Log View, one of the first things to check is the RAID status. Here, the result shows that the RAID & disk statuses are unavailable. Also, the FortiAnalyzer is unable to detect the hardware information of the RAID controller.
FAZ # diagnose system raid status Mega RAID: RAID Level: Unavailable RAID Status: Unavailable RAID Size: 0GB File System: ext4 200144GB
Disk 0: Unavailable 0GB Disk 1: Unavailable 0GB Disk 2: Unavailable 0GB Disk 3: Unavailable 0GB Disk 4: Unavailable 0GB Disk 5: Unavailable 0GB Disk 6: Unavailable 0GB Disk 7: Unavailable 0GB Disk 8: Unavailable 0GB Disk 9: Unavailable 0GB Disk 10: Unavailable 0GB ... ... ...
FAZ # diag system raid hwinfo
Exit Code: 0x00 Exit Code: 0x00 Exit Code: 0x00
2) To further check, the RAID Management Pane under System Settings will not be present in the FortiAnalyzer GUI.

3) When viewing the list of valid RAID levels, the output is blank. Also, when attempting to format the RAID, it presents an invalid RAID level error.
FAZ # execute format disk * Valid RAID levels:
FAZ # execute format disk 50 Invalid RAID level: 50 Valid RAID levels:
4)Here are a few tips to troubleshoot the issue:
i) Perform a reboot on the device. ii) Perform a power cycle on the device and collect the console logs. iii) Connect a monitor & keyboard to the device and access the BIOS.
5) If the RAID's status is still Unavailable, then this is a RAID Controller hardware failure and can open a ticket to initiate the hardware replacement process. |
